Spellcheck Is Messed Up

ok so i dont spell things good but if i see this "Vechial" I dont thing lovechild i think Vehicle. just want to let you known this it happens often with me i have 2 letter flipped and it try's and gives me something completely different.like if i miss type try's as trys its does not say try's as a option when that is right it says ttys,try,and trey.

I'm fairly sure that spell check is done through your browser (on your computer), and isn't something that is part of Roll20.  I'm not sure what it would do with "try's", since it isn't a word.  Of the 3 things you listed as examples, the first is an abbreviation, the first drops the 's, and the last is a fairly archaic form of three (I've mostly heard it regarding playing cards).  If you went with "tries" maybe that would work unless Try is a person and you need a possessive version, in which case the spell check wouldn't know that Try's is correct.
